2009-01-02Serial: UART driver changes for Cavium OCTEON.David Daney
Cavium UART implementation is not covered by existing uart_configS. Define a new uart_config (PORT_OCTEON) which is specified by OCTEON platform device registration code.

2009-01-02Serial: Allow port type to be specified when calling serial8250_register_port.David Daney
Add flag value UPF_FIXED_TYPE which specifies that the UART type is known and should not be probed. For this case the UARTs properties are just copied out of the uart_config entry. This allows us to keep SOC specific 8250 probe code out of 8250.c. In this case we know the serial hardware will not be changing as it is on the same silicon as the CPU, and we can specify it with certainty in the board/cpu setup code. The alternative is to load up 8250.c with a bunch of OCTEON specific special cases in the probing code.

2009-01-028250: Serial driver changes to support future Cavium OCTEON serial patches.David Daney
In order to use Cavium OCTEON specific serial i/o drivers, we first patch the 8250 driver to use replaceable I/O functions. Compatible I/O functions are added for existing iotypeS. An added benefit of this change is that it makes it easy to factor some of the existing special cases out to board/SOC specific support code. The alternative is to load up 8250.c with a bunch of OCTEON specific iotype code and bug work-arounds.

2009-01-028250: Don't clobber spinlocks.David Daney
In serial8250_isa_init_ports(), the port's lock is initialized. We should not overwrite it. In early_serial_setup(), only copy in the fields we need. Since the early console code only uses a subset of the fields, these are sufficient.

2009-01-02tty: We want the port object to be persistentAlan Cox
Move the tty_port and uart_info bits around a little. By embedding the uart_info into the uart_port we get rid of lots of corner case testing and also get the ability to go port<->state<->info which is a bit more elegant than the current data structures. Downsides - we allocate a tiny bit more memory for unused ports, upside we've removed as much code as it saved for most users..

2009-01-02Blackfin Serial Driver: fix bug - SIR driver stop receiving randomlyGraf Yang
Bug description: The IRDA receiver may can't receiving any more after processed some signals. To duplicate this issue is put three IRDA devices together, one blackfin, two none blackfin, they will detect each other. Let one none blackfin devices irdaping the blackfin devices, when it stopped print out ping information, it is the time that blackfin stoped receiving, the time is random. The related register bit is OK, the other devices is sending data continuously. But no interrupt come. Fixing: I tried Michael's suggestion that request the UARTx error interrupt, and reset the IRDA when found FE error. This method helps much, but it can't completely avoid stop. Reset the IRDA before every time sending the data is more safe.
